Description

Call control system of the phone

The present invention relates to a call control system of a telephone, and more particularly, to a call control system of a telephone that can be provided with a lock using a password to prevent the use of an unspecified number of telephones.

In general, a user calls a counterpart who wants to make a call by pressing a plurality of number keys provided in a key input unit formed at an outer circumference of a housing after the user lifts the handset and turns off the hook switch.

However, since the above-described general telephones are not equipped with a user control system, an unspecified number of users can use the telephones to make long-distance calls and additional service calls, so that the telephone owners may later complain about billing. There was a problem.

As a conventional prior art for prohibiting the use of a telephone by an unspecified user causing a billing problem as described above, a cover is mounted to seal the key input unit around a key input unit formed outside the telephone, and the cover is attached to a specific user. The use of the telephone by an unspecified user was prohibited by allowing only the opening and closing through a predetermined locking device.

However, in the above-described conventional non-specified user's telephone use control device, the user often does not lock the cover, which makes it impossible to control the non-specified user's telephone use, and a locking device for locking the cover (eg For example, if a particular user loses the key, there is a problem in that the cover needs to be broken.

An object of the present invention for solving the above problems is to provide a call control system of a telephone that can be provided with a locking device using a password in the telephone to make it impossible to use the phone of an unspecified number of people.

A feature of the present invention for achieving the above object is a telephone number including a key input portion 40 which is a counterpart telephone number input for requesting connection with a counterpart phone and various operation mode setting means of the phone, wherein the password of the phone A password input key 42 is provided in the memory 50 when there is a password setting signal output from the password setting key 42, the password setting key 42, the password setting key 42, and the password setting key 42. 40) record the first predetermined number of digits, and if there is a request to make a call from the telephone after the password setting is completed, the number of the first predetermined digits to be entered is compared with the password. A control device 60 for controlling the formation so that only users who know the password can use the phone. There is.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a call control system of a telephone according to the present invention.

The telephone set includes a network connection portion 10 which is responsible for connection of a communication line and transmission / reception of a predetermined signal through the communication line, a voice call unit 30 for enabling voice communication, and a password setting mode of the telephone. A key input unit 40 serving as a setting means for inputting a counterpart phone number for requesting connection to a specific counterpart video telephone by telephone, including a password setting key 42 as a selection means, and various operation modes of the telephone set; A memory 50 in which data according to the operation mode is recorded, and a control device 60 for controlling various operations of the telephone.

The voice call unit 30 includes a microphone 32 which is a voice acquisition unit of a specific caller, a speaker 34 through which a voice signal and a bell signal of a counterpart caller are output, and a voice of a counterpart caller output from the network connection unit 10. The voice processor 36 processes a signal through a predetermined processing process and outputs the signal to the speaker 34, and performs a predetermined process to output a voice signal of a specific caller input through the microphone 32 to a communication line. ).

The operation of the telephone constructed as described above is outlined below.

When the user presses a password setting key 42 provided on the key input unit 40 to input a password for call control of a specific phone, the controller 60 receives a signal output from the key input unit 40. As a reference, the phone is switched to the password setting mode, and the number of predetermined digits output from the key input unit 40 immediately after the password setting key 42 signal is input is recorded in the memory 50.

An example of the use of the telephone whose password setting is completed as described above is described below.

The network connection unit 10 is connected to the communication line and determines whether there is a call ring signal input from the other phone. If there is a call ring signal input from the other phone, the network connection unit 10 is outputted from the other phone to the control device 60 through the communication line. The input signal is subjected to a predetermined process and output. At this time, the control device 60 outputs a predetermined specific signal to the network connection unit 10 according to the state of the hook switch of the specific phone to control the formation of the call, and if the call path is formed, the control device 60 Outputs the operation signal to the voice call unit 30 so that the voice signal of the specific caller input through the microphone 32 is output to the counterpart phone, and the voice signal of the counterpart caller input from the counterpart phone through the speaker 34. To be printed.

Then, when there is no call ring signal input from the other phone and the user of the specific phone picks up the handset and the hook switch is turned off, the control device 60 stores the number of predetermined digits that are initially output from the key input unit 40. The identity of the plurality of numbers is determined by comparing with the password recorded in (50).

If it is determined through the determination process as described above that the plurality of numbers are different, the control device 60 stops the operation of the phone regardless of the number input thereafter.

When the plurality of numbers are determined to be the same according to the above determination, the control device 60 outputs a predetermined signal corresponding to the call path forming request to the network connection unit 10, and the network connection unit 10 controls the control device. The call ring signal is output to the counterpart phone via the communication line in accordance with a predetermined signal corresponding to the call path formation request outputted from 60 to control the callout formation according to the state of the hook switch of the counterpart phone.

When the call path is formed by the above operation, the control device 60 outputs an operation signal to each device constituting the voice call unit 30 so that the voice signal of the specific caller input through the microphone 32 is a communication line. Through the speaker 34, and the voice signal of the other party's voice input from the other party's phone is output through the speaker 34.

Therefore, according to the present invention, when a specific user wants to use a telephone, a telephone call is possible only by inputting a specific password set in the telephone, thereby preventing the use of the telephone by an unspecified user.

According to the call control system of the present invention operating as described above, when a specific user wants to use the telephone, the telephone call is possible only by inputting a specific password set in the telephone, thereby preventing the use of the telephone by an unspecified user. It works.
